Description of problem: I'm using iw to create a virtual interface based on my ath9k wireless interface. The newly created interface name is renameX even when I specify wlan2, for example, as name for it:

[root@Laptop pkreuzt]# iw dev wlan0 interface add wlan2 type adhoc
[root@Laptop pkreuzt]# iwconfig 
eth0      no wireless extensions.

lo        no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"XXXXX"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: XX:XX:XX:XX:XX:XX   
          Bit Rate=13 Mb/s   Tx-Power=15 dBm

          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

It also appears using phy like "iw phy phy0 interface add wlan2 type adhoc"


Version-Release number of selected component (if applicable): 3.8-2

Steps to Reproduce:

1. Enable wireless interface
2. Try to create a new interface with iw, for example with "iw dev wlan0 interface add wlan2 type adhoc"
3. See iwconfig output
